Electricity = keeps you warm, cooks your food, powers your devices. Cryptos = suck that energy out of the power grid to gamble with one another.

Miners are already looking into new business models which could actually improve the financial viability of green energy production, possibly driving down energy prices, rather than driving them up: https://www.forbes.com/sites/christopherhelman/2021/08/02/gr...

Wouldn't it make more sense to just let the price of electricity go up?

Maybe it would make more sense to you, but not to most people I think. Electricity has much better uses than cryptocurrency.

If only we had an open, decentralised mechanism to figure out what's a better use of a limited resource is.

Oh wait. That's exactly what "cost" is.

Crypto miners are pretty inefficient at heating your home.

A heat pump is more than twice as efficient as direct heat.

My heater doesn't become less effective each year, requiring replacement. While ASIC concretely implies this, GPU is not excluded if you want to remain competitive (read: generating profit)

You might say that a regular electric heater is 100% efficient, converting every unit of electricity into exactly one unit of equivalent heat.

Crypto mining hardware is >100% efficient, as it's exactly as efficient as an electric heater, but also generates revenue. Over time, others make more efficient crypto mining hardware, reducing the yield from yours. This causes your "efficiency" to gradually reduce down to 100%, but no lower.

However, nowadays we have heat pumps, which are also more efficient than our 100% benchmark, and produce additional useful heat.

All big scale BTC mines buy at industrial prices. You cannot run a mine bigger than what your wiring can support in your apartment. None of them is using the subsidised residential rate.

Are industrial prices not subsidized?

Certainly not, industrial use subsidises the residential. And businesses have to pay for their grid connection to the premises.

If you're using resistive heating, a computer is about as efficient as a space heater.

I have not recently done the math, but I'm pretty sure in my area its still more economically efficient to heat my home with natural gas than resistive heat. Obviously, emissions are a concern, future price uncertainty of fossil fuels, etc. Not the best way forward.

However, heat pumps in my area can make a ton of sense. They're far more efficient than resistive heating as long as it doesn't get practically arctic cold outside. When in decent climates they're about as economically efficient than a gas furnace.

In other words, mining crypto for heat isn't necessarily the most economical thing to do. It may just be better for you to use a heat pump and put your savings into buying crypto if ultimately having crypto and being warm is your goal.

Can you elaborate? I've seen products that do this, it must be possible.

Of course it does. It also has better uses than say gaming, so if that is the logic maybe that should be banned, too.

There is a difference between the two. That's like comparing the fuel use or exhaust of a Fiat 500 to that of a cargo ship.

You could tax income from mining instead, which would have the same effect but keep the electricity price stable for everyone else.

A challenge might be in effective tax collection, but it isn't that hard to find heavy electricity consumers.
